The function of that body pertains to campaign finance and the like. They handled a formal complaint in Sept/Nov 2008, as to the quality of evidence for qualification of Obama, they turned the matter away, and IIRC, were sued in Federal Court. Ultimate outcome (and the correct one) is that it's not their job to check the qualifications for party candidates.

So, again let’s say this is the case. The Congress, has the power to impeach and try. But would they do that in this case, the case of a fraudulent sitting president? Or would they defer the matter to a branch of the judiciary? I am trying to pin down the legal path and options that exist as a matter of law.
